Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed July 27,1904. Serial No. 218,349.

wickless annular burners,'.bi1rner-cups,

' or burner-trou hs for admitting and shutting ed the oil and Ior regulating the flowof oil to the lighted burner.

The present invention consists in certain novel combinations of peculiarly constructed and arranged parts and their accessories, as hereinafter set forth and claimed.

The leading object of this invention is to obviate sending such oil-stoves to the manufacturers for repairing or replacing the burner cups or troughs or the valves, with their appurtenances, by adapting each burner with its valve, &c., in one detachable part to be readily unscrewed and replaced at any time with a new burner.

.Other objects of the invention are to re-.

duce the number of parts, and thereby reduce cost; to reduce the number of joints, and thus to prevent leakage and accidents, and to increase the simplicity and safety of the stove,

as also to facilitate cleansing the burner either by causing the oil in the subj acent main feedpipe to dislodge any obstructions in the urner by gent y screwing the entire burner from the pipe.

A sheet of drawings accompanies this specification as part thereof.

Figure 1 is a perspective view of a twoburne'r. oil-stove embodyingthe present improvement. Fig. 2 is a side view of the burner and burner-valve detached. Fi .3represents a longitudinal section through t e burner and through the valve and burner-post and feeds tubes and Fig. 4 is a to view of the burner and the parts attached t ereto.

Like reference-letters and numbers refer to like arts in all the fi res.

a T e stove shown m Fig. 1. comprises the customa removable oil-reservoir A a subjacent oi holder B, in which a uniform oillevel is maintained in the customary way a tilting the stove or by un main feed-pipe C, leading from the bottom'of 5 5 said oil-holder and extending horizontally to the opposite end of the stove where it is provided with a removable cap D; a suitable frame E, forming sup orts for said main feedpipe and for said oi -holder and the superposed removable oil-reservoir; a combined valve and burner post F for each burner, supported by said main feed-pipe C and fixedly attached thereto by a screw-joint; an annular burner-trough G, concentric with said post F and supported thereby; a combustion-.

drum H, supported by each burner-trough, and a grating I, supported by said frame E above each.combustion-drum.

The maintained oil-level in the oilholder B is at a suitable height to'cause the oil when the valves J of the stove are fully open to fill the troughs to a proper height for supportin the maximum flame, and any overflow of oi at burnersis thus recluded.

Each of the va ve and burner posts F is constructed, as shown in Fig. 3, with oil-passages l and 2, the former extending upwardly and laterally from an oil-inlet a' at bottom to a valve-seat b in the side of the post, referably and conveniently near its top. he other oil-passage 2, hereinafter termed the upper oil-passage, extends from side toside above the valve-seat b. A feed-tube 3 embraces by its inner and lower endsaid valve-seat b and the su erjacent end of said upper oil-passage 2 an extends obliquely upward therefrom to a point above the maintained oil-level, where it is provided with an internally-screw-threaded cap 4;, which is or may be soldered fast to the outer end of the tube. A needle-valve J, having a finger-wheel 5 and the customary conical point 6 at its respective extremities and. havmg a screw-threaded stem 7, fitted to the bore of said cap t, serves to opener close the valve-seat b or to artl 0 en or close the same, soas to regu ate t e ow of oil to the burner-trough G, which communicates with the interior of said feed-tube 3 by a feed-hole 8 in its bottom. The upper oil-passage 2 extends from side to side above said valvefrom said feed-pi up .er-oil-passa vb ve-seat, a

- with said valve-seat and with thesuperjae cent and of said upper oil-passage and exhole first named. The two feed-tubes} and 9 form a pair of diametrically opposite rigid connections between the central valve and burner post and the concentric annular burner-trough, whereby the latter is securely supported 1n position and kept level, as reuired. Said upper' oil-passage 2 is prefera ly' inclined u wardly, as shown in Fig. 3, so

as to facilitate islodging downwardly into the main feedipe C any obstruction that may become lo ged in the feed-tube 9. For so cleansingeither feed-tube or either of the oilpassages in the 0st or the feed-holes in the ottom of the urner trough the quickest and easiest method is to fully open the valve J of the affected burner and gently raise and lower one end of the stove. This causes the oil within the main feed-pipe to flow back and forth through the oil-passages, and the proximity of the.,burner-trough G to the feedpipe '0 in the new arrangement promotes its success. Should it fail, the entire burner can be quickly removed, cleaned, and replaced. The ca D of the feed-pipe is only removed to drain t e feedpipe, as for repairs.

v An incombustible lighting-ring, of perfov rated sheet metal and asbestos, is represented at K in Fig. 3, and the burner-trough G, as shown in this figure and in Fig. 4, is of the peculiar construction set forth in my previous specification, forming part of patent No. 7 39,486, dated Sepetmber 22, 1903.

The lighting-rin or its equivalent may of course be of any nown or approved construction, as may also be the burner-trough.

The valve-tube cap 4 may be removable, if referred. The stove may have only one burner or more than two, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention, and desire to patent under this specification 1. The comb' ation, in

a blue-flame oilstove', of an oil-reservoir, an oil-holder in communication withsaid reservoir in which the oil is maintained at a substantially uniform level, a main feed-pipe in communication with said oil-holder, supports for said "feed-pipe, a valve and burner post rising e and constructed with an upwardly and aterally extending oil-passa in communication with the interior of said pipe at its lower end and with a valve-v seat at its upper end within the post and an e within the post above said eed-tube in communication and in communication with both at diametrically opposite points, and a su erposed combustion-drum supported by sai burnertrough.
